Abstract: 1,132,091. Moderator structures. ENGLISH ELECTRIC CO. Ltd. 9 June, 1966 [11 June, 1965], No. 24794/65. Heading G6C. In a nuclear reactor, the graphite moderator is mounted within a prestressed, cylindrical, concrete pressure vessel. To prevent misalignment of the fuel element channels in the moderator, and the standpipes in the vessel, due to dimension changes in the concrete, each vertical column of graphite blocks in the moderator is supported on a pedestal rigidly secured in the concrete. Each channel contains a graphite tube which holds the fuel and which is supported on a mounting within the pedestal. The base of each pedestal may be cooled by the pressure vessel cooling system. Spaces between the columns are provided to permit Wigher growth, graphite reflector blocks surround the core and radial restraint bars are mounted circumferentially between the moderator and concrete. Thermally induced dimension changes in the fuel channel tubing are accommodated by flexible bellows. The coolant gas may perform either a single or double pass along the channels.

IPC: B30B11/00
Filed: 1968-05-24
Abstract: 1,186,951. Hydraulic presses for moulding &c. OSTRANDER-SEYMOUR CO. 24 May, 1968, No. 24940/68. Headings B5A and B5F. [Also in Division G3] An automatic dimensional control system for a press 10 of the type wherein an article is positioned between fixed and movable platens 20, 26 bored to provide passageways for steam, oil or electrical heating comprises a transducer 121 (see Fig. 6) which is responsive to changes in the air pressure of a system including orifices 104, 105 in the platen 20 and which controls the position of a relief valve 96 (see Fig. 5) controlling the flow of hydraulic fluid to the cylinder 81 and ram 82 determining the position of the movable platen 26. The orifices 104, 105 are formed at opposite corners of the platen 20, Fig. 7 (not shown) and are accurately gauged so that a predetermined pressure is established between the platens when bearers (not shown) of substantially the dimensions desired for the article are engaged therebetween spring-loaded plungers being provided adjacent the orifices to ensure accurate positioning of the bearers. During a forming operation variations from the predetermined pressure cause opening and closing of contacts 163, 164 (see Fig. 3) controlled by the transducer 121, these contacts controlling relays 1CR, 2CR which determine the direction of rotation of a D.C. motor controlling the position of the valve 96, so that a predetermined pressure on the article is maintained. The contacts of relays 1CR, 2CR control further relays for reversing the armature current of the motor, whose speed is determined by the firing instant of a silicon controlled rectifier controlled by a unijunction transistor and adjustable RC circuit, Fig. 4 (not shown). The transducer 121 forms part of a conventional control device 118 which monitors air from a constant volume source 117 and includes members 120, 122 for respectively controlling the pressure and rate of flow of the air to orifices 104, 105. The control system of the invention is stated to ensure parallelism of the platens 20, 26 under conditions of workpiece misalignment, since the press will continue to close until the predetermined pressure corresponding to equal platen spacing at the orifices is attained. Fluid flow to the cylinder 81 may be controlled directly instead of by the relief valve 96. The press 10 is of conventional design and has the usual control circuitry to co-ordinate the movements of the platen 26 and the work-table 56 with the pre-heating and curing operations controlled respectively by the timers T1, T2. Operation of the hydraulic control system of Fig. 5 is described for each of the positions of the approach selector switch 52 enabling the operator to alter the speed of the movable platen 26 according to the type of material being formed. The switch 52 provides three modes of operation for raising the platen 26, the dimensional control system functioning as described above for each of these modes.

Abstract: 405,374. Depositing-machines. KREMMLING, A., Hamersleben, near Oschersleben Germany. Sept. 8, 1932, No. 25086. [Class 87 (ii).] A machine for forming confectionery shapes from dough, batter &c. comprises a depositor having one or more nozzles to which motion is imparted in accordance with the shape of the article to be produced, means being provided for controlling the movements of the nozzle in accordance with the forward travel of the receiving surface. As shown in Figs. 1, 2 the nozzles 5 are flexibly connected to a hopper 1 and are moved laterally and longitudinally over a depositing surface 51 by means of a frame 4 supported on a surface 3 and operated by links 11, 19 connected to bell cranks 14, 22 engaging in cam groves 16, 24 of a cam disc 17 rotated by bevel wheels 29, 30. The links 11, 19 are adjustable in slots 8, 13 and 9, 21 to vary the shape of the deposited article. The hopper is provided with known intermittently operated means for extruding the material from the nozzles 5 and for severing by a wire the deposited material from the nozzle. The material may be disconnected from the nozzle by raising and lowering the receiving surface by a cam 54, Fig. 1, or by raising and lowering the hopper or the flexible nozzles by links connected to the cam 54. The nozzle is moved in the direction of the forward travel of the moving surface 51 by reciprocating the entire nozzle operating means as shown in Fig. 3 or by reciprocating the whole machine as shown in Fig. 7. In Fig. 3 the cam disc 17 is carried in a frame 27 slidable on a guide 33, the reciprocating movement being made by a bellcrank 46 mounted on a fixed pivot 47 and rocked by a cam 44. The stroke of the frame 27 is made adjustable by moving a roller 49 in a slot 48 of the bell-crank. In Fig. 7 the machine frame 73 is mounted on rollers 76, 77 supported on a fixed base 74. The rollers are pivoted on weighted arms 82, 83. A bell-crank 93 pivoted at 86 is rocked by a screwed rod 92 connected to a rocker arm 90 bearing on a cam 89 which provides the breaking apart movement of the nozzle from the deposited confectionery. This movement may be rendered inoperative by withdrawing the rocker arm 90 from engagement with the cam by a rod 98. The reciprocating movement of the frame is obtained by a cam 103 engaging a rocker arm 101 pivoted at 102 to the frame 73 and anchored by a rod 105 to the fixed frame 74. The return movement of the frame is effected by springs. The length of the reciprocation is adjustable by moving a pivot 104 in a guide in the rocker arm 101. During the depositing the casing 73 will move forwardly at the same speed as the receiving surface and will return to its original position after the deposition of the articles is effected and extrusion is stopped, the return movement preferably being faster than the forward movement. The movements of the machine and travelling surface may be synchronized by an adjustable change-speed gear. Specification 374,530 is referred to.
